Yesterday Kim and Kourtney Kardashian went to church in Calabasas, and Kourt carried newborn daughter Penelope while Kim was on auntie duty with little Mason. As always, the ladies looked amazing, but we have to wonder what fellow churchgoers thought of Kim's sexy shoes?

On Saturday Kim tweeted, "Slumber party with Mason and Penelope!" and the next morning she tweeted the above photo of Kourt in the kitchen and added, "I woke up this morning to this ... gotta love @KourtneyKardash making breakfast."

In addition to attending a baby shower, bonding with her sister, shooting footage for their reality show and saying a few prayers, Kim also spent some time at a fitting and she tweeted a photo of several bikinis on Saturday and wrote, "Packing for something fun!!! Can't wait to share..."

Hmm, could it be another vacation with Kanye? You know, the one where he proposes?
